Seals described as expected. We'll see how long they last.

I had two Hunter PGP rotary sprinklers in my spare parts box. They both had major leaks at the under-cap seals. These replacement seals stopped the leaks and made the sprinklers ready for new use. Hunter has a video to assist with seal replacement.

Better than buying a whole new sprinkler.

unfortunately I ruined one of the 3 sets by putting them on wrong - came with no instructions at all. After getting them installed presumably correct (without leaks), now they do not recess when system moves to next zone

Works great fixing leaky Hunter PGP Ultra Sprinkler. Easy to replace and hopefully lasts forever! Going to buy a few more to have on hand. 12 Zones and many Sprinklers!

Once I figured out how to take the sprinkler apart, I installed the new retaining ring and gasket seal obtained from this purchase. But no matter how hard I tried, I could not screw the sprinkler head back on to the body. It kept cross threading. I took the new retaining ring and seal off and replaced with the old one I had just removed and the sprinkler head screwed onto the body easily. The parts in this kit must be slightly larger or otherwise different than the original and prevent the sprinkler head from properly screwing back on the body part.
